Here is a message from Google:
We are very saddened by the loss of life and the displacement of hundreds of thousands of people in Metro Manila and nearby areas caused by Typhoon Ondoy. To increase awareness of how Filipinos at home and overseas can stay up to date and aid in relief efforts, dozens of Google volunteers around the world have been working throughout the weekend and today to compile information about the disaster on this site: www.google.com.ph/landing/typhoon-ondoy.html.
The site contains a volunteer-maintained map of flood updates and persons needing rescue, the latest news from local media sources, a list of verified donation sites and emergency hotlines. It is also linked from Google.com.ph to give easy access to the 25 million Internet users in the Philippines and many more around the world.
Our effort is but one of many being organized by countless individuals and organizations across the country in the spirit of bayanihan, to help those affected by this disaster as quickly and as comprehensively as possible.
